MPMoviePlayerViewController不会播放电影，立即启动和closures

我试图用MPMoviePlayerViewController播放video，我介绍了MPMoviePlayerViewController，但1秒后，他正在解散。 这是我的代码： 。H： #import <MediaPlayer/MediaPlayer.h> @property (strong, nonatomic) MPMoviePlayerViewController *moviePlayerViewController; .M： – (void)playmovie { NSString *databaseName = @"NO.mp4"; NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentDir = [documentPaths objectAtIndex:0]; NSString *databasePath = [documentDir stringByAppendingPathComponent:databaseName]; NSURL *movieURL = [NSURL fileURLWithPath:databasePath]; UIGraphicsBeginImageContext(CGSizeMake(1,1)); self.moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL]; [self presentMoviePlayerViewControllerAnimated:self.moviePlayerViewController]; UIGraphicsEndImageContext(); [self.moviePlayerViewController.moviePlayer prepareToPlay]; [self.moviePlayerViewController.moviePlayer play]; } 请告诉我我做错了什么。 提前致谢！
